I have a machine currently running Windows 7 on a single partition hard drive.

I have installed a second hard drive. I want to install OSX86 on this second drive. I don't want the boot sector of my Win 7 installation to be corrupted by the OSX86 installation.

Is it recommended that I disconnect the 1st hard drive while I install OSX86 on the second hard drive then after installation of OSX86 re-connect the 1st hard drive and use Easy BCD to create the dual boot start menu?

Also which is the best partition type for the above scenario GUID or MBR on the OSX86 installation?

I DON'T want to screw my Win 7 installation
